JOHN 'GROENNING, OF IRON \RIVER, VVISCON SIN HORSESHOE.

A SPECIFICATION forming part of Letters Patent No. 758,358, dated April 26, 1904.

Applicationfiled July 27, 1903. Serial No. 167,160. (life model.)

To all whmn, it may concern:

Be it known that 1, JOHN Gsonnnrne, a citizen of the United States, residing at Iron River, in the county of Bayfield and State of Wisconsin, have invented a new and useful Improvement in Horseshoes, of which the following is a specification. I

My invention relates to a horseshoe, and has for its object to enable a shoe to be secured to the hoof of a horse withoutthe use of nails.

The invention consists in features of novelty as hereinafter described and claimed, reference being had to the accompanying drawings, forming part of this specification, whereon Figure 1 is a perspective view of a horses hoof with my improved horseshoe applied thereto; Fig. 2, a top plan of the shoe detached from the hoof, with its parts in the unfastened position; Fig. 3, a similar view to Fig. -2 of the shoe with its parts in the I fastened position when applied to the hoof,

(not shown;) and Fig. 4, a longitudinal vertical section through the shoe on line 44 in Fig. 3.

Like letters and numerals of reference de note like parts in all the figures.

n represents a horseshoe having the usual curved sides 1 and front or toe portion 2. On the upper face of each side 1, adjacent to the front portion 2, is an upwardly-projecting lug or ear 3, which when the shoe (4 is applied to the hoof 4 bears against the inclined surface of the hoof 4 thereat, as hereinafter more particularly referred to. The lugs 3 are preferably made integral with the shoe a, as shown, or may be of separate construction and affixed to the shoe (0 in any suitable manner.

In the upper face of and entirely across each side 1, adjacent to its rear end or heel 5, is formed a preferably dovetailed groove 6 of suitable width anddepth, which is curved or inclined from the outer edge of the side 1 toward the inner. edge of the front portion 2.,

In each groove 6 is fitted and adapted to slide a bar 7, having at its outerend, adjacent to the outer edge of the side 1, an upwardly-projecting lug or car 8, the inner ends of the bars 7, which extend along the space between the sides 1 withifithe plane of the shoe a toward its front portion 2, being hinged toa cross-bar 9, which is located between the sides .VVithin the recess 11. and around the screw- I threaded shank 10 is fitted a circular nut 12, having its outer end adapted to be rotated by a screw-driver or other tool.

It is to be here noted that the bars 7 and cross-bar 9 are preferably shaped and operate at all times within the plane of the shoe as between its upper and lower faces, thereby obviating any projections above or below the shoe a; also, that the bars 7 are so shaped as to partly surround and protect the base of the frog from injury.

In operation the shoe a, with its parts unfastened, as seen in Fig. 2, being applied to the hoof 4 with the front lugs 3 bearing against the corresponding parts of the hoof 4-, the nut 12 is rotated on the screw-threaded shank 1O until'its inner end butts against the inner end of the recess 11, in which position the outer end of the nut 12 is flush or thereabout with the outer edge of the shoe a, and by continuing to turn the nut 12 the shank 10, with its cross-bar 9 and? bars 7, will be drawn toward the inner edge of the front portion 2 and in so doing the lugs 8 at the outer ends of the sliding bars 7 are drawn inward toward each other and close upon the What '1 claim as my invention, and desire to l the said hole, a circular recess concentric with 5 secure by Letters Patent, is

A horseshoe having two opposite upwardlyprojecting front stationary lugs, a bar adapted to slide diagonally through the heel portion of each side and in the plane of the shoe between the said sides, a lug projecting upward from the bar at its outer end, the said bars being opposite to each other and hinged at their inner ends to a crossbar, a hole formed part way through and in the plane of the front portion of the shoe from its inner edge, a screw-threaded shank projecting from the cross-bar and adapted to slide through the said hole and opening from the shoe at its front edge, and a nut adapted to be rotated on the said shank within the recess, and to engage the inner end of the'recess, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN GROENNING.
